GENERAL PRECAUTIONS

1. Keep the unit more than 1 m (3.3') away from radio or TV.
2. Keep the intercom wires more than 30cm (12'') away from AC
100-240V wiring. AC induced noise and/or unit malfunction could
result.
3. Install the unit in an area that will be accessible for future
inspections, repairs, and maintenance.
4. As to other manufacturer’s devices (such as sensor, detectors,
door releases) used with this system, comply with the
Speci cations and Warranty conditions that the manufacturers or
venders present.
5. If the unit is down or does not operate properly, turn off the power
switches and unplug the power supply.
6. If it is used close to a cellular phone, the unit may malfunction.
7. The unit can be damaged if dropped. Handle with care.
8. The unit turns inoperative during power failure.
9. In areas where broadcasting station antennas are close by, the
intercom system may be affected by radio frequency interference.
10. All the units, except for door station, is designed for indoor use
only. Do not use outdoor.
11.This product, being a control unit of door release, should not be
used as a crime prevention device.
12. It must be noted in advance that the LCD panel, though
manufactured with very high precision techniques, inevitably will
have a very small portion of its picture elements always lit or not lit
at all. This is not considered a unit malfunction.
13. Door station is weather-resistant, but do not spray with high-
pressure water. Unit trouble could result.
14. For wiring, specify CAT5e/6 straight cable.
15. Due to the environmental sound around the unit, it may hinder
smooth communication, but this is not a malfunction.
16. When outside temperature lowers sharply after rainfall, etc., the
inside of camera may fog up slightly, causing a blurry picture, but
this is not a malfunction. Normal operation will be restored when
moisture evaporates.
17. Do not locate the units in a location with restricted access. It
impedes maintenance inspection or repairs. Also, unit trouble
could result.
